ABSTRACT:
An antenna apparatus for a keyless entry device is also used for receiving a radio wave transmitted by a remote control unit within a vehicular compartment. The keyless entry device and the remote control unit are configured to generate respective radio waves having a common frequency. Both radio waves can be received by at least one antenna of a column switch and a steering wheel. The antennas are placed distant from the steering shaft and common ground pattern to improve transmitting and receiving sensitivity.
